For a small business owner, employment starts practically: someone shows up, work gets done, wages get paid. But the law looks at employment from the other end. Before cash flow, before contracts, before trust, there is a basic obligation: you must know exactly who is working for you. Not in a general sense, but in a legally verifiable one. Failing to do that is how a “ghost employee” quietly enters your business.

Preventing ghost employment is not passive. The employer must actively verify identity, confirm the right to work, and link the person doing the work to the correct legal identity. In the Netherlands this includes checking a valid ID and recording the correct BSN (Burgerservicenummer,  the citizen service number used for tax and social security). It is not enough to collect documents once and file them away. The employment relationship must be real in practice: the person works under your authority, performs actual tasks, and is recognizable as your employee in daily operations.

This matters because payroll systems run on data, not faces. A common risk scenario is this: a BSN is provided, wages are paid, taxes are withheld,  but the person physically working is not the person tied to that BSN. Sometimes it is a relative, sometimes a substitute, sometimes someone without the right to work. From the employer’s perspective, “someone is doing the job” feels sufficient. Legally, it is not. The mismatch itself creates a ghost employee, even if no fraud was intended.

The responsibility does not shift because someone else handled onboarding or administration. Employers are expected to check original ID documents, compare them to the person present, keep a copy in the personnel file, and ensure the BSN matches that identity. If something changes, a replacement, a different worker, a new arrangement,  the paperwork must change too. Trust is human; verification is legal.

When this duty is neglected, the consequences follow a familiar pattern. Wage costs can be rejected. Payroll taxes and social contributions may be reassessed. Fines can apply even without bad faith. And once authorities see weak controls, scrutiny rarely stops at one employee. What felt like a small shortcut turns into a systemic risk.

None of this requires heavy bureaucracy. It requires attention at the right moment. Slow down onboarding just enough to check identity properly. Match documents to reality. Make sure the person you give instructions to is the person on your payroll. These are small acts of discipline, but they protect something much larger: the credibility of your business when it matters most.
